I hear the baby is crying, so he must be ready for a bottle.  Very carefully I put my hands under the baby, being mindful to support his neck  with one hand so his head doesn't wobble around. I hold the baby close to me, wrapping his blanket around him and cradle him in my arms.  I speak softly to the baby, I make sure his formula is not too warm and not too cold before I feed it to him.  I test the liquid on my wrist before giving it to the baby. I put the nipple of the bottle in the baby's mouth, and I ensure I'm holding the bottle at an angle so there isn't lots of air getting in his tummy.  The baby drinks all the formula and then I put him over my shoulder,  I then gently patting his back to get him to burp.

When did they start feeding the baby?
